  • Patent number: 4651686
    Abstract: In the case of a high-speed, port-controlled two-stroke internal combustion engine with crankcase scavenging with at least one cylinder having in each case at least one suction duct with an inlet port, with in each case at least one outlet duct with an outlet port and with at least one scavenging duct with a transfer port, the inlet, outlet and transfer ports being arranged on the cylinder inside, the geometrical construction of the suction duct (4) and/or outlet duct (6) is such that the engine noise is reduced throughout the speed range, while increasing the engine efficiency and while simultaneously improving the specific fuel consumption.
    Type: Grant

    Assignee: Sachs-Systemtechnik GmbH
    Inventor: Norbert Kania
  • Patent number: 4473039
    Abstract: The invention relates to a method and an apparatus for reducing to a minimum the predominant full load noise of port-controlled, two-stroke internal combustion engines by constructing the lower suction port boundary and the lower piston boundary, so that there is a gradual port opening during the upward movement of the piston and a gradual port closing during its downward stroke.

  • Patent number: 4458636
    Abstract: The invention relates to a method and to a port-controlled two-stroke internal combustion engine in which the cross-sections of the intake and outlet are so constructed in the direction of the longitudinal axis of the cylinder that in the case of an upward or downward movement of the piston, the noise-generating intake and outlet pressure gradients and amplitudes are reduced by the gradual opening of the particular intake and outlet, the piston lower edge and intakes having special constructions.

    Inventor: Norbert Kania
  • Patent number: 4420063
    Abstract: Apparatus for reducing intake noise is characterized in that the casing is provided with an air intake connection whose one end extends into the inner area of the casing and with a carburettor connection whose one end extends into the inner area of the casing and whose inlet faces the outlet of the air intake connection located in the inner area of the casing accompanied by the formation of a space having a width approximately corresponding to half the diameter of the connection which has the same diameter.
